When solving an equation with two variables, replace the variables with the values given and then solve the now variable-free equation. (Remember order of operations, PEMDAS, Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.)
Solve 8a + 2a = -8a + 8y - 6 for a in terms of y.
| 1\(\frac{1}{4}\)y - \(\frac{1}{4}\) | |
| -\(\frac{7}{8}\)y + 1 | |
| \(\frac{3}{8}\)y - \(\frac{3}{8}\) | |
| -3\(\frac{1}{2}\)y - \(\frac{1}{4}\) |
